"This system is useful although not as reliable as the 5500 or as sensitive. It provides the typical well define use of the AB Sciex instrument, and provides the ease of use of analyst software. As a tool for residue chemistry you might be better off with the 5500 or even better 6500. However for every day analysis of multiple matrices and combination of different sample types and different analytes I do suggest to use this system. This is excellent for multi-screening for pesticides or other compounds. "

"This is easy to use, user friendly and a versatile product. It comes with the user friendly software. Many people in the industry are using this and hence easy to get the troubleshooting help form anywhere in the world."
